Hey everyone, hope you're doing fine. So I was doing the Prototypes: Part 2 by Jim Hoskins and was changing the species, but it didn't work. Here is what I worte and the results.

Person.prototype.species = 'Human'
"Human"

chase.species
"Homo Sapien"

Person.prototype.favoriteColor = 'red'
"red"

chase.favoriteColor
undefined

chase.species is "Homo Sapien" instead of "Human" so something is already a little off.

function Person(){};
Person.prototype.species = 'Human';
chase = new Person();
chase.species
Person.prototype.favoriteColor = 'red';
chase.favoriteColor

is the minimal code that would work in a Javascript console.
